Last night at a fundraiser event for New York's Robin Hood charity, Chris joined the legend that is Stevie Wonder on stage.
He sang with him on Stevie's classic track "Superstition". The benefit was held at the Jacob Javits cente and raised funds to target poverty in NYC.
Two years ago the charity auctioned off the chance to join Coldplay on stage at Madison Square Gardens on 13th June 2003. The highest bid was $500,000 and the winner sang In My Place.
